e10s support? bugfixes? Rated 2 out of 5 stars

This addon is one of the few solutions for cross-browser bookmarks, but unfortunately lack of maintenance shows:
* as said elsewhere, it may un-nest your folders on first sync and even create empty duplicated folders
* When switching browsers frequently, it often bails out, asking you to override local bookmarks with a fresh copy from the server.
* such downloads sometimes end up reordering all your bookmarks (easy to fix with "sort by name"... only if that's how you had them sorted before)
* no "restartless" and "e10s" compatibility, even though at least e10s would be easy to add as the addon presumably doesn't need access to the page content to sync bookmarks

unsigned addon? Rated 4 out of 5 stars

I really love using this add-on. However, it is unsigned and disabled for Firefox v50.0. Could you please get your add-on signed?

Xmarks - DUPLICATE NAME BOOKMARK FOLDERS WOULD BE LOST !!!! Rated 1 out of 5 stars

I used it on the Chrome and Firefox. Than Sync errors started so had to stop using it on Chrome. A few days ago realized I lost duplicate name Bookmark Folders. Shame I have stopped using it and users please note: DUPLICATE BOOKMARK FOLDERS WOULD BE LOST !!!!
There is way to recover it, already done once, please go and follow their recovery info if you need it

#1 MOST AWFUL PLUGIN I HAVE EVER SEEN, IT WILL TOTALLY SCREW UP ALL YOUR BOOKMARKS Rated 1 out of 5 stars

This horrible plugin will scramble up all your bookmarks, de-nest and fragment all the sub-categories of bookmarks you had created (except for some which only get partially messed up, but those get rearranged so they're useless!), make duplicates of your bookmarks in random inappropriate places, and you'll never be able to find anything using your bookmarks again. The people who 'like' this horrid piece of crapware must have maybe one or two dozen bookmarks to deal with which they don't mind fixing all the time, but I had saved hundreds and now they're all a useless scrambled mess. So now I have to find some kind of utility that will allow me to re-organize them all, or else just delete them all and start over. I wish I could rate this piece of crap in negative stars or at least a ZERO.

IT ALSO MAKES FIREFOX HANG ALL THE TIME SO THAT YOU HAVE TO EXIT AND RESTART! Whoever is pimping this garbageware is doing a great disservice to people.

NOTE: when you go to expunge this awful software from your system you have to DELETE it from the appropriate Add-Ons areas of both Chrome and Firefox (I wouldn't recommend just deactivating, this horrid software is insidious), but then you ALSO have to go in and delete it in Control Panel => Programs and Features because that is apparently where it is set up to corrupt all your bookmarks in MSIE. If you don't do this you'll keep getting a popup message with a couple of cryptic choices that don't make much sense beyond they want to screw up your system even more, forcing you to Cancel out until you've finally deleted Xmarks there too. However, one machine I cleaned up did not show Xmarks in that area and I never figured out why, but just removing it from Firefox and Chrome was sufficient. All my machines running Xmarks used Windows 10.

Not using this add-on until e10s support is added Rated 4 out of 5 stars

The only add-on that still doesn't have e10s. It's been a while, so I'm gonna have to disable it and live without it.

Support for e10s/Electrolysis

Hi there, we are sorry to hear that you've decided to discontinue usage of the Xmarks add-on, but we do thank you for providing feedback regarding your desire to see support for e10s added.

Good Rated 4 out of 5 stars

Need Firefox e10s(Electrolysis) support.

multiprocess Firefox (e10s) support Rated 3 out of 5 stars

I have been using it for years without major issues but what about multiprocess Firefox (e10s) support? It is the only remaining add-on (among few I use) not supporting it. Would happily enable e10s support now but can't without working Xmarks. With multiprocess supported it would be 5 stars but without it is can slowly become history.

New review with updates Rated 5 out of 5 stars

See my old review first (permalink: https://addons.mozilla.org/en-us/firefox/addon/xmarks-sync/reviews/818201/)

The issues I had were related to having syncing turned on while logged into either FF or Chrome. Anyone who is having issues where you get duplicates all over, denesting/nesting errors, and all kinds of weird stuff causing you to have to constantly restore, it's absolutely caused by be logged into the browsers profile and syncing is turned on.

And to Alex E. below, I think when the developers say the issue is caused by running multiple sync tools they mean even the built-in ones. If you login to Chrome or FF you MUST turn off bookmark syncing in the respective browser option settings.

Gets 5 stars now with that in mind. Though I would STRONGLY advise that the Xmarks team make it known that even the syncing which is a builtin part of each browser will break the addon.

Hayatimi kurtariyor Rated 5 out of 5 stars

Bazen firefox bazen baska bir tarayici kullanmak zorunda kaliyorum. Birinde kaydettigim degisikligi digerinde yapmak cok zor. Ama xmarks yer imlerimi, otomatik yaparak istedigim tarayici rahatlikla kullaniyorum. Hayatimi kurtariyor.

Absolutely horrible. Rated 1 out of 5 stars

IN RESPONSE TO THE DEV: My problem was most definitely not caused by multiple bookmark syncing tools running. I attempted using the troubleshooting page prior to making this review and the issue continued for several days after.

I'm giving Xmarks 1 star only because I can't give it zero. It simply fails to do the one thing that native browser syncs can't automatically do, which is keep my bookmarks straight across multiple platforms. Since I have installed it, it has been necessary to go into the app daily to straighten out the mess it causes. Bookmarks get moved, duplicated, and de-nested. At this point, I'm removing Xmarks and I'll just manage them using the import/export tools in my browsers.

The symptoms you have mentioned here relate to running multiple bookmark syncing tools simultaneously. Please see our helpdesk here on troubleshooting your issue - https://helpdesk.xmarks.com/troubleshooting/duplicate-bookmarks-2/. If you continue to see issues, feel free to open a support ticket.

Incompatible With Multiprocess Rated 3 out of 5 stars

Firefox is rolling its new extension APIs and multiprocess. Please port your Chrome version over. Right now I cannot use this addon any more on Firefox with multiprocess enabled.

Freezes your screen, prevents browsing Rated 1 out of 5 stars

It was good once. Now, it constantly runs into syncing problems and freezes, asking you to log in. Problem is, you can't if Xmarks has frozen your screen.

Now, you can no longer contact Xmarks customer support, which immediately sets alarm bells ringing, as they now fob customers off to time consuming `forums'.

Xmarks support has not changed. If you are seeing technical issues, please open a support ticket - https://buy.xmarks.com/supportticket.php?lpnorefresh=1. This link is available on our support pages.

Useful tool Rated 4 out of 5 stars

Make sure you test it out while changing bookarks (sync it to see), just to get familiar with it. Has been a lifesaver. Needs much better documentation (ie. as a *.pdf).

Agree With Squeeky Rated 1 out of 5 stars

I am a premium user of both Xmarks and LastPass. I have used Xmarks since it was Foxmarks with varying degrees of success. As mentioned numerous times, for the past couple of years, XM causes intermittent hangs and periodically makes a mess of syncing. For example, last Friday's "sync" increased my bookmarks from 1,254 to more than 5,000 by endlessly duplicating unsorted bookmarks while deleting commonly used bookmarks. There may be either rhyme or reason to its insanity, but I don't have time to figure it out. I will be dropping Xmarks at renewal. Avoid the program until they (finally) have the bugs worked out. And - Xmarks people - if you can't "duplicate this error," you really aren't trying very hard...

Hi there - if you are seeing duplicate issues, this is due to you using multiple bookmark managing programs and they are automatically syncing. Please see the FAQ here - https://buy.xmarks.com/support.php?cmd=showfaq&id=2833.

Never once had a problem with this. Rated 5 out of 5 stars

For various reasons people seem awfully unhappy with this add ons performance.I've not had any of these happen to me even once.And I cannot recall how many years I've used this.As far as "freezing" goes this will not cause it.Check your Firefox settings.You may in fact have far to many add ons activated.Only have the ones on that you will need at the moment.If that does not work go to the support site.

Makes FF intermittently unresponsive Rated 1 out of 5 stars

I first used Foxmarks, and then Xmarks. The archived bookmarks have saved me more than once, and the syncing among several machines has been very useful.

OTOH, I have noticed for several years that FF would intermittently become unresponsive, though it would ultimately clear, before happening again perhaps 15 minutes later. My systems have fast processors, so I assumed that it was either a coding issue with FF, or that my prefs.js was "too long on the tooth" (and corrupt) after so many years and so many upgrades, or that it was a problem with one or more of my 48 extensions.

This week, I built a new system and the problem repeated (I imported my FF configuration from my main system). So, today, I spent the time to clean up my prefs.js file, and then took out my extensions one-by-one ALPHABETICALLY until I found the culprit. It is Xmarks 4.3.19. After disabling it, FF is flawless and smooth, the way it should be.

How to reproduce: Start FF, and open 10 or so web pages at one time, each in a separate tab. After 3 minutes or so, reload all of the tabs (this step probably isn't necessary). Now open Task Manager (so you can watch the FF CPU usage), and wait. First, the FF usage will drop to almost 0; then it will build, before dropping slightly again, and finally it will build and hold (in my case ~38%; Win7 with an i7-920 CPU, and Win10 with a i5-3320M CPU), and FF will become completely non-responding. This will take less than 5 minutes. If you wait, it will clear in a minute or so, though it will periodically freeze on a regular basis.

As much as I love Xmarks, I am absolutely thrilled to be rid of the problem. I could have given XMarks 5 stars for many reasons, but since it chokes my system and my user experience, I give it 1 (0, my preference, not being an option).

Useful only once and Irritating Rated 1 out of 5 stars

Tool is useful only for one initial sync and nothing else. It creates a bunch of duplicates during regular work. Avoid using it for continuous syncing at all costs. It is like this for years. None of the so called "tips n tricks" will make issues solved. I wasted a bunch of my life (daily )on manually restoring Bookmarks Sets and garbage cleanup, and reading manuals and resting settings.

useful if you format your PC Rated 5 out of 5 stars

everytime I format my PC, I use it to restore all the bookmarks and history. Also it syncs between my PC-home and PC-Word

It Does What Now? Rated 1 out of 5 stars

It does not sync.

Installed it on Chrome and Firefox. It could not sync with either one. It would not accept the password on Firefox (fine on Chrome). I reset my password (to the same password) and it worked on Firefox. Then it kept freezing up Chrome. Uninstalled it on both.

I cannot recommend this extension.
